Houston Woman Sentenced to 23 Years for 2018 Lamar High School Murder

A Houston woman, Keona Samireal Mouton, was sentenced to 23 years in prison on Tuesday for her role in the murder of 18-year-old Delindsey Mack at Lamar High School in 2018, Harris County District Attorney Kim Ogg announced.

Mouton, now 22, was convicted of murder for her involvement in the shooting death of Mack on November 13, 2018. At the time, Mouton was 16 and lured Mack to an after-school meeting where he was gunned down by two men. Kendrick Johnson, one of the shooters and a gang member with ties to multiple murders, was sentenced to life in prison in 2021. The second shooter remains at large, and the Houston Police Department continues to seek information from the public for his identification and arrest.

A third man, Dave’on Thomas, who acted as the getaway driver, was sentenced to 50 years in prison last year. The shooting was linked to an ongoing gang conflict, although Mack, a talented football player who had recently transferred from Yates High School to escape gang violence, was misidentified as a gang member on social media.

Assistant District Attorney Sarah Seely, who heads the DA’s Homicide Division, and ADA Maroun Koutani prosecuted Mouton in a seven-day trial. Mouton was certified to stand trial as an adult and must serve at least half of her 23-year sentence before being eligible for parole.

“Delindsey Mack’s parents put him in the one place that children should be safe, but Keona Mouton pulled all the strings to make his murder happen,” Seely said. “We are still looking for information and investigating who the second unknown shooter is in the case because everyone who is responsible for the murder of Delindsey Mack should be held accountable.”

Anyone with information on the case is urged to call Houston Crime Stoppers at 713-222-TIPS (8477).
